+Logging Remote Procedure Call
+#############################

+
+The Logging Remote Procedure Call (RPC) library enables receiving and managing log messages from a remote device or processor.
+
+Overview
+********
+
+The library supports the following main features:
+
+  * Log streaming, which allows for receiving log messages over RPC in real-time as they are generated by the remote device.
+  * Log history, which allows for saving log messages in a ring buffer in RAM or persistent memory, and retrieving them over RPC when needed.
+
+The library also supports retrieving a core dump stored in the remote device's memory, and setting the current time used for log timestamping.
+
+Implementation
+==============
+
+The logging RPC consists of the following components:
+
+* Zephyr's :ref:`zephyr:logging_api` backend that implements sending log messages using :ref:`nrf_rpc`.
+  It also accepts RPC commands for managing the logging backend.
+* A log forwarder, which implements receiving log messages from a remote device and passing them to the local logging subsystem.
+  It also implements RPC commands for managing the logging backend on the remote device.
+
+Configuration
+*************
+
+To enable the logging RPC backend, set the :kconfig:option:`CONFIG_LOG_BACKEND_RPC` Kconfig option.
+
+To enable the logging RPC forwarder, set the :kconfig:option:`CONFIG_LOG_FORWARDER_RPC` Kconfig option.
+
+Samples using the library
